Salam Winter! I think you have more chances of getting an answer if you write in Japanese rather than Swedish! :)
If you are a complete beginner, I would suggest that you learn the Arabic alphabet first. Meanwhile I think you should try to get exposed to Arabic conversations, songs, movies or any Arabic material even if it's in an Arabic dialect. You may not understand anything but it will really help you improve your pronunciation skills.
I also advice you to not try to study Arabic grammar at this point. You can start learning about the grammar once you have acquired enough vocabulary to make basic conversations.
And by the way, don't worry about making mistakes, Arabic speakers are usually very patient when it comes to helping people learn Arabic! :)
